Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Aquastar Benthos Professional

The Aquastar Benthos Professional is widely praised for its significantly slimmer 13.9mm case, which contributes to comfortable everyday wear and a sleek profile, and its ultra-legible dial. Reviewers note its well-tensioned bezel and an improved beads-of-rice bracelet. Some find the 42mm case size substantial for a dive watch, and its 38-hour power reserve is considered unremarkable. The watch is priced at $1,290 during pre-order. Overall, owners and reviewers rate the Aquastar Benthos Professional highly for its comfortable wearability and legible dial at the price.

CWC E9 Automatic Diver

Owners widely praise the CWC (Cabot Watch Company) E9 Automatic Diver Watch for its classic dial design, excellent lume, and exceptionally durable PVD-coated case that withstands rough use. Reviewers note the 41mm case wears close to perfectly, with a modest 12mm thickness. One owner suggests replacing the mineral crystal with sapphire to prevent scratches. On balance, owners and reviewers rate the CWC (Cabot Watch Company) E9 Automatic Diver Watch highly for its legible dial and comfortable wearability.
